ATTO

rates In teleprinting operation it is often desired to eiiect a printingof the message on a certain form, such as on a bill of accounts, a formcontaining static statements, etc. To this end forms are used which arearranged continuously on an endless sheet of paper and which areprovided with feed holes near the left and right edges of the paper forfeeding purposes. It is absolutely necessary that the position of thepaper form will be exactly the same with respect to the printing pointat both the transmitting and the receiving stations. Otherwise themessage at the receiving station would not be printed in the correctplace on the form so as to correspond with that at the transmittingstation.

In order to obtain a synchronous movement of this length of paper atboth the transmitting and receiving stations the operators at thetransmitting as well as at the receiving station will have to bring theforms into a corresponding position prior to the transmission of amessage at both the transmitting and receiving stations. This however,requires that the receiving station be an attended station, i.e., thatan operator be present for manually bringing the form into the properposition (adjusting to an identification mark) at the beginning of themessage transmission. In order to obtain form synchronism without anoperator having to be present at the receiving station, it is proposed,in accordance with the invention, to switch on the form synchronizingdevice by a signal or signal combination, such as Figs. and Who are you(tripping of the call-back device) and to feed the paper in astep-by-step manner in the vertical direction by successively depressingthe keys Linefeed and Rpt. According to a further feature of theinvention the paper feed is arranged to be interrupted by the action ofthe well known paper control contact, and a counting mechanism isarranged to count the number of paper feeding steps, until finally, uponreaching the required maximum number of steps the repeat key will be putout of operation either electrically or mechanically.

Instead of the repeat key (Rpt), a special key may be provided for thispurpose. The counting mechanism is adjustable so that the number of theline feed steps to be counted may be varied in accordance with the sizeof forms. The counting mechanism may also be modified so that it willnot comprise one, but in connection with the method used with respect tohorizontal tabulators, several riders, so that it will also be possibleto carry out a vertical tabulation in accordance with the diflerentparagraphs occurring within the text on the form.

The inventive arrangement bears the advantage over other conventionaltypes of arrangements that it may be used without further ado withteleprinters connected to the public teleprinting. network, because nospecial functions are transmitted or carried out which would be likelyto disturb the public subscriber dialling operation, or would interferein the case where a teleprinter provided with the inventive arrangementis connected with a standard type of teleprinter.

The construction as Well as the mode of operation of the inventivearrangement for obtaining the form synchronism will now be described inthe following with refatent G ice erence to an example of embodimentshown in FIGS. 1 through 8 of the accompanying drawings, in which;

FIG. 1a shows the printing paper at the transmitting station.

FIG. 1b shows the printing paper at the receiving station.

FIGS. 2-7 show various views and sections of the mechanical arrangementof the invention.

FIG. 8 shows a wiring diagram of the invention.

First of all there is shown in FIG. 1 a conventional type of paperlength 7 on which successive forms 5 are printed. These forms may beseparated along a perforated line 6 upon the being filled in by theteleprinter. On both sides of the paper length feed holes 1 are providedand each form printed on this length of paper is provided with anidentification mark 4' and with a paper contact hole 2'. At thetransmitting teleprinter station the identification mark on the form tobe filled in is brought into agreement with the marking provided on theteleprinter (FIG. 10). At the opposite station the form may be in anyother position in the teleprinter (FIG. 1b)

Thereupon the teleprinter at the opposite station Will be called andboth teleprinters will start to operate. Thereupon, at the callingteleprinter station, the Figs.- key will be depressed, which will haveto be depressed prior to operating the Who are you key. Upon actuationof the Who are you key, the engagement pushbar, denoted by 1, will beactuated by the pull-bar Who are you, and will take along the lever 2out of the position indictaed by the dot-and-dash line into the positionindicated by solid lines (FIG. 2). Apart from this operation thecall-back device will be released in the conventional manner at thecalled teleprinter station.

The stepping ratchet pawl 5 pivotally attached to the lever arm 6, whichhas been lifted by the roller 3 on the lever 2 out of the ratchet Wheel27 via the pin 4, and which is capable of acting upon the push-bar 7 forthe linefeed, as well as the ratchet 8, lifted out of the ratchet wheel27 by the action of the operating edge 10 on the lever 2 via the lever9, will engage the ratchet wheel 27 of the line counting mechanism.

This line counting mechanism consists of a ratchet wheel 27, a steppingratchet pawl 5 on the lever 6, and the coupling lever 2, as well as thesensing lever 21 (FIG. 3) which cooperates with the camplate 24, and thespiral spring 25. During the coupling process of this line countingmechanism (engagement of the pawls 5 and 6), the line contactsa and bare momentarily closed by a short lifting of the latching pawl 13, underthe action of the tooth 18 provided on the lever 2 and via thecontacting actuator 19 (FIGS. 2 and 8). The electromagnet 11; (FIGS. 5and 8) will be energized for a short time and will move the push member32' and the lever 33 towards the left via the magnet, lever arrangement(armature 48, lever 29, shaft 30, lever 31). This will release thelatching pawl 37, which, via the depressed Who are you key with thelever 42 and 41' will move the levers 39 towards the right and will thusrelease thecall-back device via the lever 37' and the releasing lever47. At the same time the coupling pressure lever 40 will engage the one-Speed clutch 43 and the transmitter driving shaft 45 will drive thetransmitting cam cylinder 44.

On the form of the teleprinter atthe opposite station and on the form ofthe teleprinter at the calling teleprinter station the name of thecalled teleprinting subscriber will now be printed. The calledteleprinting station will now automatically carry out the carriagereturn and the line feed and will transmit the signal Here is. The nameof'the called-subscriber will now be typed by the calling and the calledteleprinter.

Up to now there is no synchronism between the forms on both thetransmitting and receiving ends, and the written text is not yet typedat the place provided for it on the filled-in first form at thereceiving end (FIG. 1b). In order now to bring the form in theteleprinter of the called subscriber, into the same position as at thecalling subscriber the line feed key will be depressed and thereupon therepeat key 35 (FIG: will be actuated. In the teleprinter of the callingsubscriber the short-stroke or micro switch 49 (FIG. 4) is now closed,because the feeler 56 was permitted to engage the contact hole 2' on thepaper length 7' after being adjusted to the identification mark 4 (FIG.la). In FIG. 4 the contacts g and h of this particular teleprinted arenow closed. The transmitter driving shaft 45 will continuously drive thetransmitting cam cylinder 44 via the engaged one-speed clutch 43, and,via the teleprinter line circuit the line feed signal will becontinuously transmitted to the teleprinter set of the calledsubscriber. At each line feed operation, the counting mechanism in theteleprinter of the calling subscriber, which is engaged via the lever 2(FIG. 2), will be stepped on by one tooth. However, a line feed will nottake place, because the line feed previously carried out for thefunctional operation Who are you and Here is has turned the cam-plate 24so far that the sensing lever 21 is now positioned on the inclinedright-hand portion of the notch 23. The con tacts c and d are now closedand the relay 2a (FIGS. 4 and 8) is energized. Upon attraction of thearmature of the electro magnet, the coupling lever 53 between the lever54 and the lever 6 will be released, so that the counting mechanism willbe further transported by the line feed lever 7 and the pawl 5, but noline feed takes place via the rodding 51, 52, the pull ratchet lever 50,and the switching wheel 58 of the platen 59. However, in the calledteleprinter set a line feed will be effected until the sensing lever 56is permitted to engage the contact hole 2' on the paper length 7 Whenthis occurs the electromagnet 2a will operate the coupling pawl 53 willbe unlatched, and the line feed interrupted. The counting mechanism inthe transmitting teleprinter, as well as in the receiving teleprinter atthe opposite station will now rotate until the releasing pin 46 on theratchet wheel 27 meets the lever 14 the ratchet pawl 13 which,thereupon, will release the latching lever 2 under action of the spring16. This. lever 2 will now jump back into its normal position and willthereby disengage the pawls 5 and 8 from the teeth of the ratchet wheel27. On account of this, the ratchet wheel 27 with its camplate 24 willlikewise leap back to its initial position by the action of the spiralspring 25, which has been tensioned by the counting of the line feedoperations.

Upon lifting of the ratchet pawl 13 by the releasing pin 46 the contactsa and b will be closed. The electromagnet 1a will be energized and willput the repeat key 35 out of operation via the magnet rodding 29, 30,31, the push member 32 and the coupling lever 33, and theone-speed-clutch 43, by the engagement of the clutch pressure lever 40,will separate the transmitter driving shaft 45 from the transmitting camcylinder 44. To the operator of the calling teleprinter this is a signthatthe form in the teleprinter at the opposite station is in the sameposition as the form in his teleprinter. This condition will be noticedacoustically by the standstill of the disengaged or decoupledtransmitter driving shaft 45. In a simple way this condition may also beindicated acoustically (buzzer) or optically (lighting of a lamp).

The electromagnet 1a may be used at the same time for the tabulator inthe direction of the lines (FIGS. 6 and 7). The tabulator for ateleprinter in the line direction is described in the US. Patent2,956,120 issued Oct. 11, 1960, to G. Grinsen and J. Augustin. Thistabulator consists of several tabulating riders 60, adjustable on thetabulating bar 62, which is arranged in a swinging fashion between thelevers 63. As soon as one tabulating rider 60 meets against the limitstop 61 of the holding device 66 at the type bar carriage, thetabulating bar 63 will be pressed upwardly and the bar 64 additionallyprovided at the levers 63 will, move downwardly and close the contacts eand 1 within the housing 65. These contacts are arranged in parallelwith the contacts a and b (see FIG. 8) and will cause the attraction ofthe electromagnet 1a when too close to disengage the coupling lever 33and disable the repeat key 35 in the same manner as already described.The type bar carriage will then come to a standstill because thecontinuous transmission of the signal space" will be interrupted.

Now again a text may be transmitted and, thereupon,

by actuating the repeat key, the signal space will be transmitted untilthe next successive rider again disables the repeat key. Accordingly,the same electromagnet 1a may be used to carry out not only theadjustment as to a uniform position of the forms but also tabulation inthe direction of the lines.

Now the counting mechanism is devised in such a way that it will countthe line changes from the contact hole 2 to the next contact hole 2, inthe most extreme case e.g. in the case of a paper sheet having the sizeof DIN A4 (size A4 according to German Industrial Standards=2l0 297 mm.)so that a corresponding line feed will be obtained. When filling-informs having a smaller size, such as DIN A5 (148 X210 mm.), then therewould be too long a time before the releasing pin 46 permits thecounting mechanism to jump back into the initial position. This however,may be taken care of by inserting a second releasing pin 46 on theratchet wheel 27, permitting the line counting mechanism to return tothe initial position correspondingly earlier.

Furthermore it is conceivable that a vertical tabulation in relation tothe direction of the lines can be carried out with the aid of thecounting mechanism as well a tabulation in the direction of the lines.This may be accomplished in such a way that the releasing pin 46 and theratchet wheel or counting wheel 27 of the counting mechanism will actupon adjustable riders, which are capable of being displaced along apath concentric in respect to the counting wheel within a notch. Acontact is fixed to each rider which, upon lifting of the rider, isclosed by the releasing pin 46 and is arranged in parallel with thecontact e, (FIG. 7). Just as is the case of the tabulation in thedirection of the lines, so in this case the repeat key will beinterrupted. Provisions are made to prevent the actuation of thecontacts attached to the counting mechanism upon the return thereof toits initial position by a corresponding design of the riders or of thereleasing While I have described above the principles of my invention inconnection with specific apparatus, it is to be clearly understood thatthis description is made only by way of example and not as a limitationto the scope of my invention as set forth in the objects thereof and inthe accompanying claims.
